Meanwhile I have remodified the latest 32bit Intel MSM driver v8.9.8.1005 dated 04/05/2010, which now should support all Intel SATA AHCI and RAID Controllers from ESB2/ICH6 up to the newest 9-Series Chipset Series ones. It will be usable with all Windows Operating Systems from Windows XP up and maybe even with Windows 2000.Attached you can find this freshly customized "Universal 32bit Intel MSM driver v8.9.8.1005 mod by Fernando". Please test it by trying to get Windows 2000 installed onto your Intel 8-Series Chipset system running in AHCI mode.

I have tried your chipset downloads but when I try and install windows I get the following error.... iaStor.sys is corrupted. I haven't been able to figure out what I am doing wrong. Thanks for any help!

What sort of "chipset downloads" do you mean? Please give me the exact name of the downloaded package.Furthermore I would like to know, which Operating System you want to install.

Zitatwhen I try and install windows I get the following error.... iaStor.sys is corrupted.

This message usually comes up, when the user tries to load a 64bit textmode driver during the installation of a 32bit OS or vice versa.Please check the architecture (32/64bit) of the OS and the driver.

Due to the availability of the first mainboards with an Intel 9-Series Chipset there was the need to add the missing HardwareIDs of the brandnew "Intel(R) 9-Series Chipset Family SATA AHCI Controllers" into the INF and OEM files of my "Universally modified" 32/64bit Intel RST drivers v11.2.0.1006. Otherwise the owners of a brandnew Intel system would not be able to get Windows XP or Windows Server 2003 installed.

This situation has been the occasion for me for a complete revisement of the "universally modded" Intel AHCI/RAID drivers, which I am offering within the start post of this thread.At least I changed the following:

addition of all new or missing HardwareIDs

simplification/clarification of various Intel SATA AHCI/RAID Controller names (to make it easier for the users to differentiate them)

addition of the related DeviceID to all Intel SATA Controllers names (to make it easier for the users to choose the correct AHCI/RAID Controller during the textmode driver integration)

Request:Although I have tried to do my very best while executing all these modifications, I am not 100% sure, that the "universally modded" Intel AHCI/RAID drivers and complete packages will work for all of you.That is why I need your feedback (mentioning the OS, the sort of your special Intel SATA AHCI/RAID Controller and the driver version you have used).Thanks in advance!

Good luck with these freshly customized Intel AHCI/RAID drivers!Fernando

Ahhh, you are absolutely right!! I kept trying the 64 bit because my computer is a 64 bit windows 8.1. I am trying to dual boot windows xp on a separate hard drive and should have been using the 32 bit version. Once I did that everything worked fine! Thank you!

I integrated your remodified 32bit Intel MSM driver v8.9.8.1005 dated 04/05/2010 into the Windows 2000 Professional operating system CD using nLite, and tested today on my Biostar TZ77A / i7-2700K combination. I’m pleased to say it appears that the test was a success.

The next test starts with Device Manager to uninstall / reboot / reinstall the SATA AHCI Controller, but I’m holding off on that one for the moment, because if it doesn’t work it will probably wreck the OS.

That is the version of the Intel Chipset Device INF file, which obviously has been installed or integrated by you, and not the version of the Intel AHCI driver itself (named iaStor.sys).

Yes, you should not try to uninstall the AHCI driver or the Intel SATA AHCI Controller, because aftwerwards would not be able to boot into W2k again, because this OS doesn't have an on-board AHCI driver.If you want to change the Intel AHCI driver version, you have to install another (newer) Intel AHCI driver manually from within the Device Manager or by running the installer of a complete Intel RST Drivers & Software Set.

I just tried it and it worked fine, as it has for me in the past.

To be specific, I open Device Manager, expand IDE ATA/ATAPI Controllers, then right-click on the indented line (which reads “Intel(R) 7 Series C216 Chipset Family SATA AHCI Controller – 1E02”). Then I click Properties / Driver / Uninstall.

The system asks for a restart, which I allow. The rebooted system asks to install a disk drive, which I allow, and asks for a reboot, which I allow. The “Found New Hardware Wizard” opens, looking for the SATA AHCI Controller. I direct it to yours. The system asks for a restart, which I allow.

Windows 2000 Professional loads the desktop, all right and tight as before.

Sorry for the delay here, but I finally have my Z87 motherboard and Haswell processor back in action, and this morning I was able to test your AHCI driver using the 8-Series chipset with Windows 2000 Professional. I’m pleased to report the OS installed without incident, and I have it running in true SATA mode.

Your drivers have been very helpful in allowing me to push my favorite operating system forward into the next generation of Intel hardware. Thank you, and keep up the good work.

Thanks for your feedback!It is great, that you succeeded with the Windows 2000 installation in AHCI mode by using the Intel MSM driver 8.9.8.1005, which had been modded by me, and it was a pleasure for me, that I was able to help you.

Yes, everything is correct with your installation.Now to your questions:

The "Intel(R) ICH8M Ultra ATA Storage Controller - 2850" has nothing to do with the "Intel(R) ICH8M SATA AHCI Controller". It is the Intel P-ATA Controller, which manages the Intel IDE port(s) of your mainboard.

The SCSI filter driver iaStorF.sys has not been installed, because Windows 8 doesn't need it. This has to do with the UNMAP command for SCSI drives (similar to TRIM for SATA), which is natively supported by Windows 8/8.1 (contrary to Win7).

I have now testet the new 12.9.3 driver on my Sabertooth x58 with crucial m4 ssd in ahci single mode - run on the Intel Sata2 ICH10 controler instead marvel sata3 because the performance is much better.

Compare to the driver v12.8.11 is not much diverence, also very stable - but compare to v13 drivers, which are very much toddle during the benchmark tests, is v12.9.3. now my first choice...

Overall seems that the read performance is simelar and the write performance is a bit better then the v12.8.11 driver.
